I posted a few days ago about my 115 Johnson that had sat for 9 months and was frozen up. I soaked filled the two cylinders that were out past the exhaust ports with PB Blaster and poured some more PB Blaster in the other 2 cylinders and let it soak a couple of days. It was still froze up so I soaked it again in Marvel Mystery Oil for 3 more days and still couldn't break it free. My neighbor who is an auto mechanic and a pretty good all around handyman suggested I remove the heads and spray the cylinders good with corrosionx. I did this on the left side which I have reasons to believe is the bad side for 2 more days. I haven't got the heads off the right side yet due to a stuck bolt and a lack of time to work on it but I have just continued to soak that side as I have been doing.
I have put about 140 lbs of torque on the flywheel nut and she won't budge a bit. I have tapped a little on the pistons with a hammer and a block of wood but don't want to over do it. I'm going to post a link to my previous thread which is a little more detailed in case more information is useful. Anyway it looks like I'm going to be tearing this motor down when I get the time. Does anybody have any other suggestions I might try to break it free in the meantime? Oh one other question I had been meaning to ask, with stuck rings would there be any play at all in the flywheel? Mine is solid, no play at all.
